Ofw MCP Server

OurFamilyWizard MCP

A Model Context Protocol server that connects Claude to OurFamilyWizard, giving you natural-language access to your co-parenting messages, calendar, expenses, and journal.

[!WARNING] AI-developed project. This codebase was entirely built and is actively maintained by Claude Sonnet 4.6. No human has audited the implementation. Review all code and tool permissions before use.

What you can do

Ask Claude things like:

• "Show me my recent OFW messages"
• "What's on the kids' calendar next week?"
• "List recent expenses and tell me what I owe"
• "Add a journal entry about today's pickup"
• "Draft a reply to the last message from my co-parent"

Requirements

• Claude Desktop
• Node.js 22.5 or later (node:sqlite is the cache backend)
• An active OurFamilyWizard account

Acknowledgement of Terms

By using this MCP server, you acknowledge and agree to the following:

1. This server accesses your own OurFamilyWizard account. Auth happens via your own credentials. It does not — and cannot — access your co-parent's account, your children's accounts, or anyone else's.

2. OurFamilyWizard's Terms govern your use of this server, just as they govern your direct use of OFW. There is no explicit anti-scraping clause; the governing language is broader:

Users may not obtain or attempt to obtain any materials or information through any means not intentionally made available.

And on credentials: "You are solely responsible for (1) maintaining the strict confidentiality of assigned Authentication Methods, (2) instructing any individual to whom the assigned Authentication Method is shared ('Authorized User') to not allow another person to use the Authentication Method." OFW does contemplate "Authorized Users" and third-party-enabled integrations — but the account holder remains responsible.

You are agreeing to those terms — read by the maintainer 2026-05-23 — every time you invoke a tool in this server.

3. Personal, family use only. This project is not affiliated with, endorsed by, sponsored by, or in partnership with OurFamilyWizard, LLC or its parent. It is a personal automation tool for the named account holder. Do not use it on behalf of a co-parent without their consent, do not share credentials with anyone, and do not use it to bulk-extract another family's data.

4. OFW is a court-of-record platform. Messages, expenses, calendar entries, and journal entries on OFW may be entered into legal proceedings — including custody, divorce, and parenting-plan-modification cases. Anything this server writes to OFW (drafts you save, events you create, expenses you log) will appear with the same legal weight as if you had typed it yourself. Do not let this MCP send a message, create an event, or log an expense that you have not read and approved. Review every write operation before confirming.

5. You accept full responsibility for any consequences — both technical (account warnings, suspension) and legal (anything OFW records about your account activity). The MCP author is not your attorney; if you're using OFW in connection with an active legal matter, talk to your actual attorney before automating anything.

This section is the maintainer's good-faith summary of the terms — it is not legal advice and does not modify or supersede OurFamilyWizard's actual ToS.

Installation

1. Clone and build

git clone https://github.com/chrischall/ofw-mcp.git
cd ofw-mcp
npm install
npm run build

2. Add to Claude Desktop

Edit your Claude Desktop config file:

• Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json

Add the ofw entry inside "mcpServers" (create the key if it doesn't exist):

{
  "mcpServers": {
    "ofw": {
      "command": "node",
      "args": ["/absolute/path/to/ofw-mcp/dist/index.js"],
      "env": {
        "OFW_USERNAME": "your-email@example.com",
        "OFW_PASSWORD": "your-ofw-password"
      }
    }
  }
}

Replace /absolute/path/to/ofw-mcp with the actual path where you cloned the repo. On Mac, run pwd inside the cloned directory to get it.

3. Restart Claude Desktop

Quit completely (Cmd+Q on Mac, not just close the window) and relaunch.

4. Verify

Ask Claude: "What does my OFW dashboard look like?" — it should show your unread message count, upcoming events, and outstanding expenses.

Authentication

ofw-mcp tries three auth paths in order; whichever succeeds first is used. Existing setups keep working unchanged.

1. Env-var credentials (legacy, recommended for Claude Desktop). Set OFW_USERNAME + OFW_PASSWORD and the server logs in via OFW's form endpoint. This is the path shown in the Claude Desktop config above.
2. fetchproxy fallback (no env vars needed). When the credentials are absent, the server reads localStorage["auth"] once at startup from your already-signed-in ourfamilywizard.com tab via the fetchproxy browser extension. After that one read, all OFW API calls go directly from Node — the extension is not in the request hot path. Install the fetchproxy extension (Chrome Web Store / Safari .dmg), sign into OurFamilyWizard once, and the MCP just works. If you have multiple OFW accounts and want them to use separate caches, set OFW_CACHE_IDENTITY to a label per profile.
3. Error. If neither path is available, the server tells you exactly which fix to apply. Set OFW_DISABLE_FETCHPROXY=1 to skip the fetchproxy fallback entirely (turns missing credentials into a hard error — useful in headless CI).

Credential options (env-var path)

Option A — env block in Claude Desktop config (shown above, recommended):

"env": {
  "OFW_USERNAME": "your-email@example.com",
  "OFW_PASSWORD": "your-ofw-password"
}

Option B — .env file in the project directory:

cp .env.example .env
# edit .env and fill in your credentials

Environment variables always take priority over the .env file. You can also pass them directly on the command line:

OFW_USERNAME=you@example.com OFW_PASSWORD=yourpass node dist/index.js

Available tools

Read-only tools run automatically. Write tools ask for your confirmation first. The Write mode column shows the minimum OFW_WRITE_MODE a tool needs to be available at all — see Write protection below.

Write protection (OFW_WRITE_MODE)

The "Confirm" permission above is a hint to the MCP host — a host configured to auto-approve tools (or a user who clicked "always allow" once) would leave nothing between model output and a sent message. Because OurFamilyWizard is a court-of-record platform, the server also supports a structural gate: set OFW_WRITE_MODE in the server's env block and tools above your chosen level are never registered, so no host setting or prompt-injected instruction can invoke them.

Unrecognized values fail closed to none, with a warning on stderr — a typo never silently grants write access.

Troubleshooting

"0 messages" — Claude may have read the notification counts rather than the actual messages. Ask explicitly: "List the messages in my OFW inbox" or "Use ofw_list_message_folders then ofw_list_messages".

"OFW auth: set OFW_USERNAME + OFW_PASSWORD, or install the fetchproxy extension…" — neither auth path is configured. Either fill in the env block in your Claude Desktop config, or install the fetchproxy extension and sign into ourfamilywizard.com in your browser.

"fetchproxy fallback failed" — the env-var path wasn't configured and the extension couldn't be reached. Confirm the fetchproxy extension is installed, signed into OFW, and that it's running (open the extension popup). If you want to disable the fallback entirely, set OFW_DISABLE_FETCHPROXY=1.

403 Forbidden — wrong credentials. Verify your username/password at ofw.ourfamilywizard.com.

Tools not appearing in Claude — go to Claude Desktop → Settings → Developer to see connected servers and any error output. Make sure you fully quit and relaunched after editing the config.

Can't find the config file on Mac — in Finder press Cmd+Shift+G and paste ~/Library/Application Support/Claude/.

Security

• Credentials live only in your local config file or .env
• They are passed to the server as environment variables and never logged
• The server authenticates with OFW using the same login flow as the web app
• Use a strong, unique OFW password

Development

npm test         # run the vitest suite
npm run build    # tsc → dist/, then esbuild bundle → dist/bundle.js
npm run dev      # node --env-file=.env dist/index.js (requires built dist)

Main is protected. All changes land via PR — open with gh pr create --label <release-notes-label> and add ready-to-merge once you're satisfied with the auto-review feedback. See CLAUDE.md for the full PR + release flow.

Auth flow

Auth resolution lives in src/auth.ts. Three paths, in priority order:

1. Env vars present → src/auth-password.ts does the legacy OFW Spring Security form login:
   1. GET /ofw/login.form — establishes a session cookie
   2. POST /ofw/login — submits credentials, returns { auth: "<token>" }
2. Env vars absent (and OFW_DISABLE_FETCHPROXY unset) → @fetchproxy/bootstrap reads localStorage["auth"] + localStorage["tokenExpiry"] once from the user's signed-in ourfamilywizard.com tab, then closes the bridge.
3. Nothing configured → throws with both fixes spelled out.

Either path returns a Bearer token to OFWClient, which then operates from Node with Authorization: Bearer <token> — fetchproxy is not in the request hot path. On 401 the client re-resolves auth and replays once. Tokens are cached for 6h (env-var path) or until tokenExpiry (fetchproxy path).
